F2-19 records the state of input terminals X1 to X16 when the latest fault occurs. Each 
terminal is allocated with a bit. The corresponding relationship is as follows:
Bit0: X1; Bit1: X2; …… Bit15: X16
F2-20 records the state of input terminals X17 to X20 when the latest fault occurs. Each 
terminal is allocated with a bit. The corresponding relationship is as follows:
Bit0: X17 Bit1: X18; Bit2: X19; Bit3: X20
F2-21 records the state of relays Y1 and Y3. Each relay is allocated with a bit. The 
corresponding relationship is as follows:
Bit0: Y1; Bit1: Y1F; Bit2: Y3; Bit3: Y3F
F2-22 and F2-23 record the phase A/B escalator speed when the latest fault occurs. The 
actual record is phase A/B pulse cycle (unit: 10 ms) or the number of phase A/B pulses a 
second. They can be determined based on F2-10, F2-11 and F2-12.
